| 22:11 | Fix a possible user-after free following OOM in the EXISTS-to-JOIN optimization. (Leaf check-in: 498ee8d514 user: drh tags: trunk) | |
| 20:28 | Adjustments to test/incrblob4.test so that it works on both Linux and Mac in spite of error message differences between those platforms. Minor change to termIsEquivalent() to provide 100% MC/DC. (check-in: 720387f860 user: drh tags: trunk) | |
| 19:53 | New optimizations to detect early when queries return no rows due to tables being empty. This includes the EXISTS-to-JOIN optimization that tries to transform EXISTS constraints into additional terms of the FROM clause. (check-in: e33da6d5dc user: drh tags: trunk) | |
| 19:02 | Fix a problem with the fix in [5cb8e342e1]. (check-in: 043ff54fb7 user: dan tags: trunk) | |
| 18:44 | Fix another problem with running fts5 integrity-check in SQLITE_DEBUG builds, this one causing an assert() failure. (check-in: 5cb8e342e1 user: dan tags: trunk) | |
| 17:28 | Enable the EXISTS-to-JOIN optimization if the outer query has no FROM clause. (Closed-Leaf check-in: 1b9b124f9a user: drh tags: empty-table-optimizations) | |
| 14:54 | If SQLITE_DEBUG is defined, fts5 does extra checks as part of integrity-check. Ensure that errors from these extra checks are only reported if the other, normal, tests all pass. This fixes a test case in fts5corrupt3.test that was failing if SQLITE_DEBUG was defined. (check-in: 98a53fb276 user: dan tags: trunk) | |
| 12:37 | Fix test case results in FTS5 that were changed error message improvements in [48044a6b57c0a16c] but which were omitted from that check-in. (check-in: e1f8e0240b user: drh tags: trunk) | |

| 20:47 | Only run preupdate-hook tests in incrblob4.test if the preupdate-hook is enabled in the build. (check-in: 56314b6b53 user: dan tags: trunk) | |
| 18:35 | Merge the latest trunk enhancements and fixes into the empty-table-optimizations branch. (check-in: f15cdf0757 user: drh tags: empty-table-optimizations) | |
| 16:28 | Rework the fix to the problem described by forum post b9647a113b so that it provides a more complete fix that covers cases that were not resolved by the original fix, and so that it does not cause performance regressions. (Leaf check-in: 4084ac20f4 user: drh tags: branch-3.50) | |
| 16:19 | Rework the fix to the problem described by forum post b9647a113b so that it provides a more complete fix that covers cases that were not resolved by the original fix, and so that it does not cause performance regressions. (check-in: 28db0d152d user: drh tags: trunk) | |
| 15:40 | Simplifications to the row-value IN operator logic. Do not let the query planner accept a WhereLoop for a row-value IN operator that uses the same index column more than once. (Closed-Leaf check-in: d2adf61f21 user: drh tags: redundant-idx-columns) | |
| 14:42 | Work around the Emscripten 4.10 regression described in Emscripten ticket #24656. (check-in: db96ff7bbc user: stephan tags: branch-3.50) | |
| 12:11 | Work around the Emscripten 4.10 regression described in Emscripten ticket #24656. Problem reported off-list by BrickViking. (check-in: c385475b25 user: stephan tags: trunk) | |
| 11:37 | Avoid invoking the preupdate hook from within sqlite3_blob_write() if the cursor is already invalid. (check-in: 9f335b9a4e user: dan tags: trunk) | |
| 10:54 | Back out the fix at [ba7d5bad32ad6aac] because it does not always work and because it causes a performance regression. Add new test cases for row-value lookups of indexes that contain redundant columns, three of which are currently failing. This branch is seeking an improved solution to the redundant index column problem for row-value lookups. (check-in: ad8ddcefab user: drh tags: redundant-idx-columns) | |
| 02:23 | Fix a parsing error introduced by the addition of the ability to disable comments. (check-in: 602f8a639c user: drh tags: branch-3.50) | |
| 02:18 | Fix parser error introduced by [325e547a2195571e]. See forum post 095dbfc06e5. (check-in: 4eefab4494 user: drh tags: trunk) | |

| 15:01 | Experimentally add sqlite3.oo1.DB/Stmt.wrapHandle(), which allow DB/Stmt instances to wrap a (sqlite3*)/(sqlite3_stmt*) optionally with or without taking ownership of it. The intent is to enable mix-and-match use of the C API, the oo1 API, and any other hypothetical API which exposes those pointers. oo1.Stmt.parameterCount is now a property access interceptor like Stmt.columnCount is, but that doesn't change how it's used.

| 18:38 | Propagate the -ldl and -lpthread flags, if needed, into sqlite3.pc, per request in forum post 44a58c807353162f. This resolves usage of that pkgconf file on some OSes. (check-in: b4db6ddeed user: stephan tags: branch-3.50) | |
| 18:32 | Add 'reconfigure' target to Makefile.in to re-run the configure script with the same flags it was generated with. (check-in: c60907e77b user: stephan tags: trunk) | |
| 17:20 | Propagate the -ldl and -lpthread flags, if needed, into sqlite3.pc, per request in forum post 44a58c807353162f. (check-in: 64f5f14322 user: stephan tags: trunk) | |
| 14:24 | Merge fixes from trunk into the empty-table-optimizations branch (check-in: 6f98b16d21 user: drh tags: empty-table-optimizations) | |
| 12:25 | Fix harmless compiler warnings. (check-in: 13af4acebe user: drh tags: trunk) | |
| 11:48 | Remove an ALWAYS() added by [960a8e6fc91f4] that turns out to be false in some cases of malformed SQL. (check-in: cc8171461b user: drh tags: trunk) | |

| 16:05 | Fix a few cases where LIMIT clauses that were part of scalar sub-queries on virtual tables were not being passed to xBestIndex methods correctly. (check-in: 960a8e6fc9 user: dan tags: trunk) | |
| 15:50 | Improvements to sqlite3_vtab_rhs_value() logging in the ext/misc/vtablog.c extension. (Closed-Leaf check-in: 25131ee84f user: drh tags: vtab-limit-fixes) | |
| 14:28 | Make handling of LIMIT clauses in correlated sub-queries on virtual tables more efficient. (check-in: 7214cb2a5b user: dan tags: vtab-limit-fixes) | |

| 13:19 | If the LHS for an EXCEPT or INTERSECT operator is empty, skip over the computation of the RHS. (check-in: 13f096ae8a user: drh tags: empty-table-optimizations) | |
| 11:47 | Improve the bytecode for joins such that it exits earlier if it determines that no output is possible. (check-in: 2d2b61cba4 user: drh tags: trunk) | |

| 12:49 | When attempting to optimize "expr AND false" to "false" and "expr IN ()" to "false", take care not to delete aggregate functions in the "expr" as doing so can change the meaning of the query. (check-in: 355c7902de user: drh tags: branch-3.50) | |
| 12:43 | When attempting to optimize "expr AND false" to "false" and "expr IN ()" to "false", take care not to delete aggregate functions in the "expr" as doing so can change the meaning of the query. See forum thread f4878de3e7. (check-in: 77397bd67d user: drh tags: trunk) | |

| 23:17 | Restart this branch using a different take: add new "v2" routines instead of refactoring the old ones, which eliminates any performance impact or risk of behavior change for existing APIs. None of this code is actually called from anywhere yet. (check-in: b0b1b4ccb9 user: stephan tags: column-text-blob-v2) | |
| 22:15 | Initial experimental internal changes needed to support a hypothetical sqlite3_column_text/blob_v2(), as discussed in forum post 402a837960d9de45. This is just the first step: this change needs to cascade upwards a couple of levels, remove one level of porting-crutch API, and go through performance comparisons before we'll know whether it's really feasible. make devtest passes but there are corner error cases which require more precise testing to ensure that there are no visible changes in behavior. (Closed-Leaf check-in: 730c6a623e user: stephan tags: column-text-blob-v2) | |
| 20:19 | Compute WhereLevel.addrBrk and .addrHalt early so that those labels can be used to abort loops early. Use this to improve performance on two more of the cases described by forum post 52651713ac. (check-in: 6fc0b9ac23 user: drh tags: empty-table-optimizations) | |
| 16:41 | Strive to skip the evaluation of scalar subqueries that are part of a larger expression if the result from the scalar subquery does not change the result of the overall expression. (check-in: 0083d5169a user: drh tags: trunk) | |
| 12:14 | For all binary operators, try to avoid computing subquery operands if the other operand is NULL. (Closed-Leaf check-in: d86eb16283 user: drh tags: optimize-null-values) | |
| 11:46 | Preliminary refactoring of the XDG_CONFIG_HOME support to support the pending addition of other XDG-configurable options. In response to forum post 31db1a23f9. (check-in: 69b9244e3a user: stephan tags: shell-xdg-vars) | |
| 11:01 | Minor API doc typo fixes from brickviking. (check-in: 581a088df7 user: stephan tags: branch-3.50) | |
